Chinese camp tent frame.
the wooden frame was made of juniper limbs from native trees, and the area contained little or no underbrush. That lack of vegation, along with the rocky soil, leads me to believe that no wild fires have been in the region since 1868, and therefore the tent frame has not been burned. The frame itself covers a depression in the earth, similiar to other sites of Chinese encampments. There is/was another tent frame near this one, however it had collapsed.
